I need some more info, how old is that dist ? Is it points, stock type HEI or aftermarket? Did you have it serviced or just throw it back in again? Your cam timing really has nothing to do with actual dist timing. If the engine was balanced with that damper you need to replace it with that same size damper. Could you give me the cam part # so I can see the recomended rpm range and such. Are you using stock type heads or Vortec, Vortec heads take way less timing than stock style 23 degree ones.

I have a rather large cam in my ride and it idles at 1k rpm. My initial timing is 14 degrees with a total of 35 at 2500 rpm. Timing lights need to be recalibrated every so often but if the one you have is not a dial back style go buy one.
